The New York capacity market, orchestrated by the New York Independent System Operator (NYISO), is a critical component of the broader New York energy markets. This intricate market ensures that utilities and retail electric providers have access to reliable capacity resources to meet peak demand while maintaining grid stability.
In this comprehensive guide, we’ll unravel the complexities of these markets, providing you with a deep understanding of NYISO’s integral role in shaping the energy landscape of nearly 20 million New Yorkers.

NYISO market overviewÂ
Like other Independent System Operators (ISOs) and Regional Transmission Organizations (RTOs), NYISO does not generate electricity nor does it own transmission lines. Rather, it coordinates with power producers, utilities, and other stakeholders to ensure the state’s electric grid meets the current and future electricity demands of nearly 20 million New Yorkers. Â
The current iteration of NYISO was formed in 1999, but its roots go back to the mid-1960s. To ensure grid reliability after the Northeast Blackout of 1965, which plunged nearly 30 million people in the northeastern U.S. and Canada into darkness, seven investor-owned utilities in the state formed the New York Power Pool (NYPP). Â
In 1997, following the Federal Energy Regulatory Commission’s (FERC) restructuring of the energy industry, the NYPP filed a request to become an independent system operator. That application was approved and the NYISO market took control of the state’s electric power system in 1999.  Â
Today, NYISO operates a wholesale energy market as well as a capacity market, which it calls the Installed Capacity (ICAP) market — both integral parts of the broader NYISO market. These markets ensure that utilities and other stakeholders can meet the state’s electric grid demands effectively.
NYISO capacity market explained
In New York, capacity management is a critical function overseen by NYISO to ensure compliance with the grid reliability rules established by the New York State Reliability Council (NYSRC). This includes adhering to the resource adequacy and Installed Reserve Margin (IRM) requirements, which collectively define the New York capacity needed to meet both current and future demand peaks, thereby ensuring grid stability and reliability.
NYISO’s capacity management, particularly through its Installed Capacity market, ensures that utilities and other retail electric providers can fulfill the requirements set by the New York State Reliability Council (NYSRC). These NYISO capacity auctions are competitive events where market participants secure the necessary resources to reliably meet peak demand. Through these auctions, NYISO facilitates the effective distribution of available capacity, which can include traditional generators as well as renewable sources like solar and wind.
NYISO hosts seasonal auctions twice a year — one for the summer capability period, which runs from May through October, and one for the winter capability period that spans November through April. Supply resources are listed from lowest to highest cost, with demand significantly impacting price — the higher the demand the greater the volume of higher-priced resources must be purchased. Â
Market participants can also participate in NYISO’s monthly spot auctions to help meet demand or make up for unexpected generator outages. Â
